Noobie crayfish question

[808bait]

First of all, is it better to keep crayfishes in a tank with "deep water" or in a small pond with "shallow" water? I've recently caught crayfishes and I have them set up in both situations. The small ones are in a 55 gal tank and seem to be doing very well. The large ones are in a 5 ft diameter pond (water is about 6-10 in deep). Well, in the pond, there are bricks and rocks that break the surface. My question is, why do crayfishes climb those rocks and lean over to one side? Seems like they're trying to get air or something. In the 55 gal tank, there are driftwood that breaks the surface as well, but I don't see the little ones doing that. Any info would be great. Thanks.

I know right now i have two female crawfish in a 65 gallon with about 150 babies. I put in some cement block peices and covered the bottom with marbles. All i have in with them is a air stone. I do water change on it 3 times a week due to no filtration. Also they are in deep water and it doesnt seem to bother them at all. Some times you will catch a few of them swim to the top but swim right back down. Actually i think deeper the better because they are great escape artists. We feed them either crushed up flake food or usually worms everyother night. THEY LOVE worms.

Deep or shallow doesn't really matter so long as adequate oxygen and suitable water quality are provided. They're just like any other aquarium subject, except for the fact that they're stronger and more capable of clambering out of tanks...Always make sure the lid is heavy enough that they can't lever it up. Good luck with it.

A thought just occurred to me. The crayfish you see on the sides of stones in your pond might, as you believe, be trying to get some oxygen. Sometimes, if a pond's deeper, and full of rotting organic matter, oxygen levels drop, hence, everything comes up top. If that's not the case, they might just be trying to get warm.
